Visit Notes

Sunday, 13th September 2009

It is a real shame that this monument is so ruined, because it has a very special and rare feature for a portal tomb : decoration!

The site is in a small farmyard just metres away from outbuildings and a lane runs right past the site. At the time of this visit there was a heap of gravel and an oil drum next to the stones, but nothing amongst the stones themselves.

The structure is in such disarray that it is impossible to tell exactly what is still standing in its correct place. It looks as though there is one portal stone and one chamber orthostat in their original positions, but I might be wrong.

In the centre of the heap of stones and slabs one has a clear oval arrangement of cupmarks. The ring is not complete and there is another cupmark next to them.

Portal tombs are what most people wrongly refer to as dolmens. They are, to me at least, the most strikingly designed of the megalithic tombs. They are called portal tombs because they have two large upright stones, usually very well matched, in front of the chamber that seem to form a doorway.

Resting upon the portal stones and the chamber a large capstone rests (sometimes there are two capstones - see Knockeen (County Waterford)), usually at an angle of around 22 degrees from the horizontal. Although these were originally incorporated into one end of a long cairn there are none left in this state today, although traces of the cairn can sometimes be seen upon the ground. The portal stones can be up to 3.5m tall, which combined with a thick capstone can produce an imposing monument over 5m tall. Capstones can reach in excess of 70 tonnes, with that of Browne's Hill (County Carlow) being estimated at over 120 tonnes.

Often betwen the portal stones there is a door slab, blocking the width of the entrance, but not always the full height. Door slabs are either half height, three quarter height or full height, describing the amount of the portal that they obstruct. All portal tombs would have had door slab, but this has often been removed to facilitate entry into the chamber.

Quite rarely the portal stones are the same height as the chamber and the characteristic slope of the capstone is created by the profile of the capstone (see Glendruid (County Dublin)).

A large stone stood upright to form the wall of a passage or chamber, usually in a passage tomb, but can also refer to the walls of any tomb.

About Coordinates Displayed

This is an explanation of (and a bit of a disclaimer for) the
coordinates I provide.

Where a GPS figure is given this is the master for all other
coordinates. According to my Garmin these are quite accurate.

Where there is no GPS figure the 6 figure grid reference is master
for the others. This may not be very accurate as it could have come
from the OS maps and could have been read by eye. Consequently, all
other cordinates are going to have inaccuracies.

The calculation of Longitude and Latitude uses an algorithm that is
not 100% accurate. The long/lat figures are used as a basis for
calculating the UTM & ITM coordinates. Consequently, UTM & ITM
coordinates are slightly out.

UTM is a global coordinate system - Universal Transverse Mercator -
that is at the core of the GPS system.

ITM is the new coordinate system - Irish Transverse Mercator - that
is more accurate and more GPS friendly than the Irish Grid Reference
system. This will be used on the next generation of Irish OS maps.
